Qt Location: Qml Map element fails to load tiles with certain rotation angles and clipping enabled

Map tiles are not loaded if rotating the Qml Map component with angles other than 0, 90, 180, and 270 degrees and with clipping enabled.

Steps to reproduce:
1.) Open the mapviewer example shipped with the Qt Location plugin.
2.) Open the MapComponent.qml file and add:
<code>
rotation: 45
clip: true
</code>

The example will show markers but not the map tiles. When clipping is set to "clip: false" or the rotation angle is 0, 90, 180, or 270° then the tiles are loaded.
